Wild Fire Risk
HIGH FIRE DANGER IS FORECAST
All fine dead fuels ignite readily and fires start easily from most causes. Unattended brush and campfires are likely to escape. Fires spread rapidly and short-distance spotting is common. High-intensity burning may develop on slopes or in concentrations of fine fuels. Fires may become serious and their control difficult unless they are attacked successfully while small.

FIRE DANGER CODES (FFDC, SFDC, GFDC)


The FWI is further refined into indices that represent the Fire Intensity likely in the three vegetation types (Forest, Scrub & Grasses). These three codes are divided into five fire danger classes (Low, Moderate, High, Very high & Extreme) and calculate the fire intensity in kilowatts per square metre (kw/m^2).

FOREST ................ VERY HIGH, (3380)
Based on predicted generated "fire intensity (kw/m^2)" in highly flammable forest type vegetation (conifer, eucalypt). This code denotes how difficult it would be to control a fire in this vegetation type should one start.
SCRUB ................. EXTREME, (7070)
Based on predicted generated "fire intensity (kw/m^2)" in flammable scrub type vegetation (tea tree, broom, gorse, manuka). This code denotes how difficult it would be to control a fire in this vegetation type should one start.
GRASS.................HIGH, (1542)
Based on predicted generated "fire intensity (kw/m^2)" in grass type vegetation (dry grass, tussock). This code denotes how difficult it would be to control a fire in this vegetation type should one start.
